Isuzu MU-X vs Audi Q3

What's the difference?

So, engine aside, not much new for the 2024 MU-X, but I can confidently say this: if you’re not towing big loads all of the time, then the 1.9-litre turbo-diesel won’t just save you cash at the dealership, but at the service station, too.

I hate how this car has challenged my long-held belief that coupe SUVs are silly. Even more so than other notable examples I’ve driven, like Mercedes’ GLC 53.

It’s so sleek and stylish, drives beautifully, and is so packed with immersive technology that I had to triple check the price. The Sportback takes everything good about the Q3 and makes it even better looking with barely a penalty to practicality. Bravo.

If you like the look of the 2023 Isuzu MU-X, then boy have I got good news for you, because the changes to the 2024 model occur under the bonnet, and nowhere else, really. That means you get the same simple, boxy exterior design, which emphasises capability over fanciness.

Yes, the MU-X design is more dependable than daring, but I reckon it works, with the three-row SUV cutting a fairly handsome figure, even if it is yet to receive the design tweaks just rolled out on the updated Isuzu D-Max.

Inside, though, it definitely presents as a little utilitarian, with some plastics that feel like they could survive a nuclear blast, and the 7.0- and 9.0-inch central screens both feel a little underwhelming by modern standards.

It all feels very comfortable and hard-wearing though, which is probably every bit as important, given the MU-X’s target market.

This is the best-looking coupe SUV I’ve seen. Do you agree?

You could argue the Porsche Macan is up there alongside it, and I’d agree, but it’s also at least $20K more expensive.

Volvo’s XC40 maybe comes close in terms of exterior appeal, but it isn’t a coupe.

You can see elements of Lamborghini Urus (an Audi subsidiary) in the air dams and roofline, and there’s a complexity to it which hints at the tech within.

In fact, I’d say this Audi is so swish I kind of understand now. This is what coupe SUVs are meant to be about. Redefining the ‘SUV look’, inside and out.

Why pretend SUVs are about off-roading anymore? They’re really about comfort and convenience in the confines of a city.

Of course, the ‘inside’ bit comes naturally to the Q3, which has a swish, simplistic, but wonderfully advanced cockpit.

The design is upright, but not imposing, spacious, but not barren. The slight driver focus of the vents, touchscreen, and controls is noted and appreciated.

Both screens are ultra-high resolution, sharp and crisp to look at, and it adds so much to the lustre of everything you use, fitting seamlessly with the sharp and detailed lines in the dash. The fully adjustable LED interior ambient lighting is wholly unnecessary but does make it a nice place to be at night, and changing the colours entertained my family members no end.

Virtual Cockpit is still unrivalled for its aesthetics and ease of use, too. The wheel is even notable for its neat proportions and comfortable shape.

What don’t I like? The tall plasticky shift-knob still looks like it belongs in a base-model VW Polo, and some padding around the centre tunnel for the knees would be appreciated.

Practicality has always been a sizeable MU-X perk, regardless of the engine. 

That starts with seven seats, and a back row where actual full-size humans can spend time — and there are not many three-row SUVs you can say that about.

I’m 175cm tall and while I wouldn’t pick row three as my first choice, I’d happily sit back there for short hops.

The middle row, too, is pretty spacious, though it is lacking in a few creature comforts, with just the air-con vents (but no temp controls) and a couple of USB ports to keep you company.

And remember when I said the brand was promising the 1.9-litre engine wouldn’t cost much in terms of capability? Well, Isuzu says the braked towing capacity for models fitted with the smaller engine is 3000kg, while the payload figure increases — now up to 735kg — mostly because the new engine is about 70 kilos lighter. Models fitted with the 3.0-litre turbo-diesel are still rated to tow 3.5-tonne. 

The MU-X stretches 4850mm in length, 1870mm in width and 1815mm in height and it sits on a 2855mm wheelbase, which means while there’s plenty of cabin space it’s not too ridiculous to park.

You’ll find 311 litres of boot space with all three rows in place, growing to 1119 litres with the second row folded flat and 2138 litres with just the front two seats in action.

Every MU-X model will offer at least 800mm in wading depth and 230mm ground clearance, too.

We like the practicality in the regular Q3, but is the Sportback too compromised? Let’s take a look

The front two passengers are treated to a spacious and airy cabin, with loads of glass and space for your elbows. You can adjust the height of the centre box to suit your driving position, and there are no complaints when it comes to leg- or headroom.

Tech spills out of the dash and into your hands. USB-A, USB-C and wireless connectivity are available to you. In fact, wireless Apple CarPlay is as revolutionary as keyless entry.

You set it up once and that’s it. Just turn the car on, leave the phone in your pocket and the media system does the rest. The cost is a slight input lag, but the payoff of just being able to throw your phone in the charging bay or simply leave it in your pocket and forget about it is well worth it.

Storage areas are abundant for front passengers with big cupholders with a large centre slot for a phone or wallet perhaps, the large wireless charging bay and a small but useful centre console box.

There are also small bottle holders in the doors and a decently-sized glove box.

A small annoyance comes from the high-resolution screen. Some items become too fine to accurately jab at without taking your eyes off the road, particularly in Apple CarPlay mode. Thankfully all essentials, like the climate and volume controls have physical dials.

Visibility out the front and sides for the driver is fantastic, although there’s no denying the smaller rear aperture in the Sportback’s design makes seeing out the rear a bit more difficult.

Rear passengers are treated to a customizable area. The rear seats are on rails, and I found my legroom to be more than adequate in the standard, furthest-back position. I could have moved the seat about 20 per cent further forward without running into issues.

Height is a different story. I’m 182cm (6.0ft) tall and fit okay with maybe a couple of centimetres space above my head. My slightly taller brother (around 185cm) had his head pretty much up against the roof. The standard Q3 had no such issues, but it’s worth considering if you plan to regularly transport taller family or friends.

The back of the rear seats are clad in plastic which looks nasty but will be good for those with kids, and rear passengers can make use of two USB-C ports, a 12V outlet and dual adjustable air vents on the back of the centre stack.

Boot space comes in at 530 litres (VDA) with all seats in their default positions which proved more than enough for our largest CarsGuide suitcase, some duffel bags, and camera equipment.

It can be adjusted up to 1400L with all the seats stowed. Apparently, this is no less than the regular Q3, which would make sense as the space is meant to be measured to the parcel shelf, before the more aggressive roofline starts to cut its shape.

Our test car is the 35 TFSI (which means it has the least powerful Q3 engine) in Launch Edition trim. In Sportback form, I think it looks a million bucks, but was surprised and taken aback by how affordable it is by premium car standards.

Wearing an MSRP of $56,450, this Q3 isn’t bad value, especially when lined up against similar spec competitors like Volvo’s XC40 (Design - $56,990). BMW’s ageing X1 sDrive 20i is significantly cheaper up-front ($48,500) but will require a fair few option packs to be on-par with this Audi. And even then there are some tech items which the Q3 will have over it.

We don’t know how much Mercedes-Benz’ GLB will cost yet, although it’s a different small SUV beast with a chunky backside and seven seats.

Standard spec includes 19-inch alloy wheels, an impressive 10.1-inch multimedia touchscreen, Android Auto and digital radio with wireless Apple CarPlay (!), wireless charging, 10-speaker audio system, Wi-Fi hotspot, built-in nav (with online traffic and other services), 10.25-inch ‘virtual cockpit’ digital dash, dual-zone climate control, leather seating, heated and powered front seats with heated steering wheel, auto dimming rear view mirror, keyless entry with push-start, LED headlights, as well as surround parking sensors and cameras.

The options list is surpisingly short and affordable at this end of the market, consisting of a Bang & Olufsen surround speaker system ($900), full paint finish bumpers ($450), park assist ($300), ‘Matrix’ LED headlights ($1300 – why? The standard ones are fine), panoramic opening sunroof ($2080), and electronic dampers ($1700). You’ll note all are luxuries and won’t make or break a sale for anyone.

It’s also worth noting the Q3’s relatively high standard spec complements its almost segment-bending dimensions, which will have some considering whether they really need something slightly larger again like an X3, GLC, or Audi’s own Q5.

Let’s focus on the new engine option here, with the 1.9-litre turbo-diesel delivering 110kW and 350Nm. They don’t sound like massive numbers, but Isuzu makes the point that the torque delivery is wide, with maximum grunt available from 1800rpm to 2600rpm, and 300Nm available from 1550rpm to 3700rpm, meaning there’s power there when you need it.

The new engine pairs with a six-speed Aisin tramsission and delivers power to two or all four wheels.

Powering 35 TFSI variants is a 1.4-litre turbocharged four-cylinder petrol engine, producing 110kW/250Nm. It’s mated to a six-speed dual-clutch automatic transmission and powers the front wheels only.

An all-wheel drive version with a 2.0-litre engine is available further up the range.

Another perk of the smaller engine is a smaller fuel bill, with the 1.9-litre turbo-diesel promising to drink 7.4L/100km on the combined cycle - almost a litre less than the 3.0-litre 4x4 model, which is more like 8.3L/100km. 

Emissions drop, too, with the smaller engine rated at 196g/km of C02 combined, compared with 220g/km on for the 3.0-litre 4x4 model.

Impact on the hip pocket? Well, fewer trips to the service station for one. Isuzu says the 80-litre fuel tank should deliver almost 1100km of driving between refills.

The 35 TFSI has a claimed/combined fuel consumption figure of 7.3L/100km, against which I scored 8.4L/100km on my weekly test.

That number's very good for something this size, probably helped along by the 35 TFSI's relatively light 1545kg kerb weight.

Oddly, and unlike most VW Group vehicles with similar drivetrains, the Q3 35 TFSI does not have a stop/start system.

The 35 TFSI requires 95 RON premium unleaded petrol and has a 60-litre fuel tank.

First things first, you can absolutely tow with the smaller MU-X engine. In fact, we attached a load weighing close to its 3.0-tonne maximum and the Isuzu just hunkered down and got to work.

It must be said, though, it’s nowhere near as effortless as when you have the bigger 3.0-litre turbo-diesel engine up front, which dispatches heavy loads clinically and easily.

The smaller option has to try harder and rev higher, and while it’s easy enough on downhill runs or flats, it’s noticeably slower when heading up hill.

It does demand the question of how often you’ll be attaching close to its rated maximum on the towball, though. If it’s often, the bigger engine is definitely for you. But if it’s occasionally, or your tow loads are lighter, you can definitely make do with the 1.9-litre option.

On the road, the 1.9-litre engine’s power delivery is actually pretty well suited to the MU-X. It’s not fast, of course, but the width of the torque band helps deliver grunt when you need it (to a point) especially in the low-end, and I reckon the whole experience is a bit smoother and quieter than with the bigger engine, too.

You are missing some of that effortless grunt, of course, and you still can’t escape the usual diesel noise that permeates the cabin, but the lower fuel use for lower power feels like a fairly decent trade. 

It won’t be for everyone, and cross-country travellers and towers will no doubt go for the bigger unit, but for everyone else the 1.9-litre is a pretty sensible option.

The Q3 offers a slick, modern, and comfortable drive, but not one without its flaws.

The ride is superb. A great balance of sportiness and damping, the Q3 keeps it stable in the corners, but comfortable over bumps. This was helped along by comfort-spec Hankook tyres on our car, and the 19-inch wheels proved to be a sensible size.

The only thing which seemed to transmit unpleasantness into the cabin was the dampers going out of frequency on rutted roads. I couldn’t help but note the similarity of the Q3’s ride characteristics to those of the new VW T-Roc, a size under.

Inside is quiet and refined, and all of the Q3’s features are ergonomic and easy to use to the point where you take it for granted. But with the Sportback’s cropped rear window, seeing out the rear isn’t as easy as it is in the regular Q3.

The engine has sufficient power when the boost, and subsequently peak torque, sets in, the trouble is this can all happen very suddenly.

There’s a delay when stomping on the go-pedal, which is replaced a full second thereafter with a surge of torque. It takes a bit of getting used to working in a moment of restraint while you wait for power to arrive.

Get impatient, and the Q3 will simply spin its wheels off the line. It’s not a problem isolated to this car, but one I also found in other VW Group vehicles with similar drivetrains. The Tiguan comes to mind.

A neat trick is setting the Q3 into the sportier ‘Dynamic’ mode and then switching the transmission from ‘S’ to the regular Drive. This gives you the best of a more responsive powertrain without having the transmission hang around in gears for too long.

The six-speed can still be caught out fairly easily as it tries to be ‘smart’ about its changes to a fault. I wonder how well its computer would go about learning your driving patterns long-term.

All up, the Q3 offers a nice balance of SUV comfort and hatch-like sportiness thanks to its light frame. The turbo engine has its small issues, but there are no red flags here for urban commuters.

The Q3 has a maximum five-star ANCAP safety rating (awarded in 2018) which covers all variants.

The advanced safety systems standard on the Launch Edition include auto emergency braking (up to 250km/h, detects pedestrians and cyclists up to 85km/h), lane keep assist with lane departure warning, blind spot monitoring, rear cross traffic alert, adaptive cruise control (with stop and go function), and driver attention alert.

Several of these items, like the adaptive cruise are not standard on the base car and require an optional ‘Comfort Package’. Tick that box if the Launch Edition is sold out by the time you’re reading this.

Expected safety inclusions are six airbags, electronic stability and brake controls, and hill assist systems..

Every Isuzu MU-X model gets a six-year, 150,000km warranty, as well as five years of capped price servicing, and up two seven years of roadside assistant. 

The service are 12 months or 15,000km, and each service costs $449 per year, or a total $2245 over five years.

Audi’s standard warranty offer of three years and unlimited kilometres is annoyingly short, but not unexpected from a premium brand.

The pressure is on though, with Mercedes-Benz and newcomer, Genesis, now offering five years of warranty coverage, as well as Japanese stalwart Lexus offering four years.

Audi was even considering making a promotional five-year unlimited kilometre warranty permanent at the time of writing, so hopefully that has come to pass by the time you’re reading this review. Time will tell.

Where Audi makes ground back though is its very competitive service pricing. We’d strongly recommend bundling in an Audi ‘Genuine Care’ service plan at the time of purchase which will make your servicing much cheaper.

Three years of servicing for the Q3 under this scheme is $1610, while five years is $2630 it’s worth it. All Q3s require servicing once every 12 months or 15,000km.
